BELT-CLEAN ER.

SPECIFICATION forming part of Letters Patent N o. 689,881, datedDecember 31, 1 901.

Application filed February 16. 1901. Serial No. 47,684. (No model-l To@ZZ whom it may concern,.-

Be it known that I, HENRY S. HOY, a citizen of the United States,residing at l-Iarvey, county of Cook, State of Illinois, have invent- 5ed a certain new and useful Improvement in Belt-Cleaners, of which thefollowing is a specification.

My invention relates to devices for cleaning or scraping the surfaces ofbelts, and parro ticularly to a form of cleaner especially adapted forcleaning the inner surface of the elevator or carrying belt of anexcavatingmachine, such as a grading and ditching machine.

Objects of my invention are to provide a simple and effective form ofbeltcleaner adapted to scrape the inner surface of the lower leaf of thebelt and discharge the dirt or other substance at either side thereofand zo to provide a construction tending to facilitate the discharge andprevent clogging.

To the foregoing and other useful ends my invention consists in mattershereinafter set forth and claimed.

My invention is applicable to any desired construction of excavating orgrading and ditching machine in which the excavated soil is taken by anendless conveyer-belt arranged to pass about suitably-located rolls, acon- 5o struction of machines of such class being shown, for example, inLetters Patent of the United States to Edwards and Gray, No. 636,506,dated November 7, 1899.

The accompanying drawing shows in perspective a belt conveyer orelevator equipped with a cleaning device embodying the principles of myinvention, the cleaner and adjacent parts being shown in full lines,while the balance of the conveyer is shown in dotted lines.

As thus illustrated, the wedge shaped cleaner A is preferably arrangedbetween the upper and lower leaves of the belt B, it being observed thatthe corner or angle a of the cleaner points in an opposite direction tothe movement of the lower leaf l). With this arrangement the downwardlyand outwardly diverging portions a' of the cleaner will bear against theupper surface of said lower leaf 5o l), it being understood that theapplication of the cleaner in this manner is for the purpose of removingobjectionable accumulations from the inner surface of said belt, suchaccumulations occurring,\f0r instance, in operating the carrying-belt ofan ordinary grading and ditching machine. These flaring oroutwardly-diverging portions d are, it will be observed, preferablystraight and so formed as to present straight edges to the belt andsmooth unbroken deflecting-surfaces to 6o the dirt or other substancecarried by and moving with the belt.

I/Vhile I do not limit myself to any particular construction, it will beseen that in the present embodiment of my invention the side bars C ofthe excavatorelevator or conveyer are provided with arch-like portions0, located at the terminals of the portions a of the deflector andproviding at such points a couple of lateral discharge-openings 'c'. 7oThrough these openings the dirt or other substance collected by thecleaner is discharged at either side of the conveyer. It will beobserved that the ends of the cleaner project within saiddischarge-openings in such manner as to make substantially the entirewidth of each opening available for the purpose of discharge. It will beunderstood that any sllitable construction or arrangement can be adaptedfor securing the cleaner in place. 8a Thus it will be seen that myimproved beltcleaner is simple and effective and adapted to removesubstances from the surface of a belt without danger of clogging andthat my invention is particularly applicable to eXca- S5 vating-machinesfor the purpose of removing objectionable accumulations of dirt from theinner surface of the carrying-belt, and especially from the innersurface of the lower leaf of the endless conveyer-belt employed in grad-9o ing and ditching or like soil-excavating machines in which loose soilcommonly finds its way in between the leaves of the belt t0 an extent tointerfere with the proper working of the same over the belt-rolls atopposite ends of the elevator-frame. The portions of the belt which insuch machines more particularly require cleaning are the marginalportions of the inner surface of the lower belt-leaf, and hence whilethe union of the roo two oblique portions of the cleaner or scrapershown at a point at or near the middle longitudinal line of thebelt-leaf forms a more coinplete cleaner or scraper and also permitseach oblique scraper portion tobrace and steady the other itisunderstood that the scraper portions which are arranged oblique to theline of movement of the lower belt-leaf need not for some purposes beunited at their inner ends, but, to the contrary, can be more or lessseparated at such ends and that,lif desired, they can also in such casebe connected. together by a transverse rod or bar, and also that suchscraper portions could be relatively spaced along the beltthat is tosay, they need not be set opposite one another, as shown.

From the foregoing it will be seen that the stationary wedge or V shapedscraper is arranged with its apex pointing in a direction opposite tothe direction in which the lower leaf of the belt travels and with itsopposite sides secured to opposite sides of the frame and that thelatter is at such points adapted to form lateral discharge-passages forthe soil scraped from the belt; also, that the oblique sides of thisscraper which are opposed to the travel of soil along with the lowerbelt-leaf form deflectors and guides, along which the scraped-up soilwill be caused to slide toward the dischargepassages by reason of thefor ward travel of the belt. v

What I claim as my invention isl. The combination in anelevating-conveyer for excavating-m achines, of the endless belt; theframe; and a stationary wedge 'or Vhfaped scraper arranged over thelower Vleat' of the belt and having its apex pointing in a directionopposite to the direction of travel of such lower leaf, and its oppositeside portions secured toopposite sides of the frame, said frame beingadapted'at such points to provide passages for the discharge of soil,and

the oblique sides ot' the scraper being ar- `the elevator or conveyer ofan excavatingmachine, the side bars of said elevator or con# veyerformed with arch-like portions provid; ing a couple of lateraldischarge-openings, and a wedgeshaped cleaner arranged be-' tween theupper and lower leaves of said belt, andcomposed of two downwardly andout'- wardly diverging portions, the corner or angle of said cleanerpointingin an opposite direction to the movement of said lower leaf, andthe outer ends of the cleaner extending into said discharge-openings insuch manner as to make the greater part of each opening available forthe purpose of discharge, substantially as described.

3. The combination of the belt B, the side bars of the elevator-frameprovided with the arch-like portions c, providing dischargeopenings c',and the cleaner A composed of the outwardly and downwardly divergingportions a, substantially as shown and described.
